Answer:
259.15
Step-by-step explanation:
![\bf \stackrel{\textit{cost of the pens}}{0.40x+15}\qquad \qquad \qquad \stackrel{\textit{cost of the sportpacks}}{1.50y+30} \\\\\\\ \stackrel{x=500}{[0.40(500)+15]}~~+~~[1.50y+30] \le 3330 \\\\\\ 200+15~~+~~1.5y+30\le 3330\implies 245+1.5y \le 3330 \\\\\\ 1.5y\le 3085\implies y\le \cfrac{3085}{1.5}\implies y\le \cfrac{6170}{3}\implies y\le 2056\frac{2}{3}](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7B%5Ctextit%7Bcost%20of%20the%20pens%7D%7D%7B0.40x%2B15%7D%5Cqquad%20%5Cqquad%20%5Cqquad%20%5Cstackrel%7B%5Ctextit%7Bcost%20of%20the%20sportpacks%7D%7D%7B1.50y%2B30%7D%0A%5C%5C%5C%5C%5C%5C%5C%0A%5Cstackrel%7Bx%3D500%7D%7B%5B0.40%28500%29%2B15%5D%7D~~%2B~~%5B1.50y%2B30%5D%20%5Cle%203330%0A%5C%5C%5C%5C%5C%5C%0A200%2B15~~%2B~~1.5y%2B30%5Cle%203330%5Cimplies%20245%2B1.5y%20%5Cle%203330%0A%5C%5C%5C%5C%5C%5C%0A1.5y%5Cle%203085%5Cimplies%20y%5Cle%20%5Ccfrac%7B3085%7D%7B1.5%7D%5Cimplies%20y%5Cle%20%5Ccfrac%7B6170%7D%7B3%7D%5Cimplies%20y%5Cle%202056%5Cfrac%7B2%7D%7B3%7D)
or namely 2056 sportpacks if we toss away the fraction.
I believe the answer is C and F.
Hope this helps!

Answer:
3. Simplifying
4 multiplication property of equality.
5. simplifying
Step-by-step explanation:
y/2 -21+21 = -15+21
To get to the next step we add -21+21 on the left and -15+21 on the right
We are simplifying on each side
Then we multiply by 2 on each side for the next step
We use the multiplication property of equality.
Finally we simplify in the last step
